Annotation of researchv9/ipc/README, revision 1.1

1.1     ! root        1: The connection server is made up of a number of intertwined programs.
        !             2: These programs are roughly divided into three groups:
        !             3: 1) Managers (/usr/ipc/mgrs/*) -- These are non-terminating programs started
        !             4:    by /etc/rc.  One group consists of dialers that listen for and place calls on 
        !             5:    particular networks (dkmgr, tcpmgr, tpcmgr, udpmgr).  The next group are
        !             6:    programs used to configure the different networks (dkhup, kdiload, ipconfig,
        !             7:    dkipconfig, routed).  Finally is the service manager (svcmgr) that offers
        !             8:    the standard user services such as login and program execution.
        !             9: 2) Commands (/usr/ipc/bin/*) -- These programs are run by users to perform
        !            10:    network functions such as remote login and remote executions.
        !            11: 3) Servers (/usr/ipc/servers/*) -- These are programs started by `svcmgr'
        !            12:    when called by a command on some other system (telnetd, Rpush, Rpull).
        !            13: These programs have been shipped to all of our systems.
        !            14: 
        !            15: Connection service programs communicate using streams.  They rendezvous by
        !            16: mounting onto files in the directory /cs.  A /cs has been shipped to all our
        !            17: systems.  It is protected to be writable only by root and bin.  This ensures
        !            18: that unprivileged users may not usurp rendezvous points.  A number of user
        !            19: accessable moutn points (tcp.1024-tcp.1124) exist for use by telnet and ftp.
        !            20: 
        !            21: Configuration files are needed by `svcmgr' to know what services to
        !            22: offer and for whom to offer them.  These are the files /usr/ipc/lib/auth,
        !            23: /usr/ipc/lib/auth.local, /usr/ipc/lib/serv, and /usr/ipc/lib/serv.local.
        !            24: /usr/ipc/lib/auth and /usr/ipc/lib/serv are shipped from bowell and contain
        !            25: the base set of services and authentications.  The *.local files should NEVER
        !            26: be shipped.  They take precedence over the base set and are used to configure
        !            27: system peculiarities.
        !            28:
